Measurement of Grinding Temperature of Active Grains Using Infrared Radiation Pyrometer with Optical Fiber

The temperature of the cutting grains on the grinding wheel just after cutting is measured using a new type of infrared radiation pyrometer with optical fiber and InAs cell. The mean temperature of cutting grains is hardly influenced by the wheel depth of cut or the workpiece speed, but decreases with increase of the wheel speed. The maximum temperature of cutting grains at the cutting point is approximate to the melting point of the work material of steel. The change in the working conditions of cutting grains after every revolution of the wheel is observed.
